Improvement in apparatus for turning the leaves of music



UNITED STATES PATENT OFFICE.

CHARLES HEYER, OF RACINE, WISCONSIN.

Specification forming part of Letters Patent No. 118,935, dated September l2, 1871.

To all whom it may concern: v

Be it known that I, CHARLES HEYER, of Racine, in the county of Racine and in the State of Wisconsin, have invented certain new and useful Improvements in Device for Turning Music; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon making a part of this specification.

The nature of my invention consists in the construction and arrangement of a device or apparatus for turning sheet-music, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the ann exed drawing, in which- Figure 1 is a side View of the machine set up for use. Fig. 2 is an end View ofthe same. Fig. 3 is a section of the revolving drum, showing the journal upon which theweighted rope acts, and Fig. 4 is an edge View of the portfolio or cover in which the music is placed.

A represents a stand of any suitable size and construction. From this stand or bed rise two standards, B B, in which the journals of a drum, C, have their bearings, one of said journals, u, having` a rope or cord, b, attached to it. This cord passes up over a pulley, D, arranged in an arm from an upright post, E, and from said pulley the cord passespdown through a tube or cylinder, I-I, and to the end of the cord is attached a weight, G, In other two standards, B B', rising from the bed A, is hung a frame, I, on pivots in its sides, so that it can swing back and forth. Rubber bands or springs d (l are attached to the lower end of. the frame I and operating in opposite directions, so that when the frame is swung to either side said bands or springs will bring the frame back in a vertical or almost vertical position. In the frame I is a slide, J, which moves up and down in the same and is held upward by means of rubber bands or springs c c, and a cord, f, connects the lower end of said slide with a treadle, K. rlhis treadle is provided with springs l1l h to hold it up.

This machine is set a suitable distance from the music-stand, say so that the frame I will be about iifty inches to the left of the upper right-hand corner of the music. The music is placed in a portfolio or cover, L, provided with hooks k lo, as shown vin Fig. 4, the first and last sheets being held by said hooks while the intervening sheets are loose. To the drum C is attached a cord, m provided at regular intervals with springcatches t fz'. NVhen this cord is wound around the drum the cord b will be entirely free from the journal u., or not around the journal. The cord m is then passed through a hole, n, in the frame I, and drawn out, thus unwinding it from the drum and at the same time winding the cord b on thejournal a. The slide J holds each springcatch fi from passing through the hole n until the slide is lowered by the treadle K, and thus it will be seen that the weight G operating through the cord b on the journal of the drum will revolve the same and wind up the cord m whenever the slide J is lowered to allow the passage of the spring-catches t' fi.. These catches are placed on the upper right corner of the music-sheets not held by the hooks k 7c, and the treadle being arranged in any suitable manner so that it can be touched or operated either by hand or foot, it follows that whenever desired to turn one sheet it is only necessary to press down the treadle for an instant to allow the preceding catch fz to pass through the hole a, when the drum C turns or revolves, winding up the cord turning the sheet. The catch on this sheet releases itself when brought over to the left, and stops at the hole a until desired to turn the next sheet in the same manner. The frame I, swinging on pivots and provided with the openings d (l, prevents breaking of the cord m or sudden jar to the device. The slack cord or thread between the catches fi yi is laid in between the sheets of music.

Having thus fully described my invention, wh at I claim as new, and desire to secure by Letters Patent, is-

1. The drum C, with journal a., cord b, weight G, pulley D, and tube H, all constructed and arranged substantially as and for the purposes herein set forth.

2. The swinging frame I, provided with hole a, slide J, and springs d l and c, all substantially as and for the purposes herein set forth.

3. The cord m with spring-eatehesz' z' attached In testimony that I claim the foregoing I have to the drum G, and operating substantiallyv as and hereunto set my hand this 24th day of April, 1871. for the purposes herein set forth. CHARLES HEYER.

4L. The combination of the drum C, oord b,

Weight G, swinging frame IWith the slide J, and Witnesses:
